Answer:
The author of Uncle Tom's Cabin based the story on her own contact with escaped slaves.
Explanation:
Harriet Beecher Stowe, the author of The Cabin of Uncle Tom, was an abolitionist and author of more than ten books. Although Stowe had never set foot in the American South, she consistently published A Key to Uncle Tom's Cabin, a real work documenting the veracity of her description of the lives of the slaves in the original novel.
Born in Litchfield, Connecticut, and raised in Hartford, she was the seventh daughter of Lyman Beecher, a religious congregational abolitionist minister in Boston, and Roxana Foote Beecher, sister of also famed Protestant pastor Henry Ward Beecher. In 1832, her family moved to Cincinnati, another fervent city of the abolitionist cause, where her father became the first president of Lane Theological Seminary. In that place, she obtained her own knowledge of slavery and the underground railroad, and was motivated to write Uncle Tom's Cabin, the first great American novel with an African-American hero.
